Gravitational form factors of the proton from near-threshold vector meson photoproduction
Xiao-Yun Wang, Fancong Zeng, Jiyuan Zhang
We embark on a systematical analysis of the quark and gluon gravitational form factors (GFFs) of the proton, by connecting energy-momentum tensor (EMT) and the near-threshold vecto…
Analysis of the contribution of the quantum anomaly energy to the proton mass
Xiao-Yun Wang, Jingxuan Bu, Fancong Zeng
Inspired by the recent Hall C and GlueX measurements of photoproduction, a systematic analysis of the contribution of quantum anomalous energy (QAE) to the proton mass is car…
Gluon gravitational form factors of protons from charmonium photoproduction
Xiao-Yun Wang, Fancong Zeng, Quanjin Wang
Inspired by the recent near-threshold photoproduction measurements, we discuss gluon gravitational form factors (GFFs) and internal properties of the proton. This work presen…
First extraction of the proton mass radius and scattering length from photoproduction
Xiao-Yun Wang, Fancong Zeng, Quanjin Wang +1
As it involves the lightest physical states excited from the vacuum by the vector quark current, near-threshold photoproduction is considered a possible way to research the p…
The scattering length based on near-threshold charmoniums photoproduction
Xiao-Yun Wang, Fancong Zeng, Igor I. Strakovsky
Under the framework of Vector Meson Dominance model, the value of scattering length can be expressed as a function of the ratio between total cross section and , wher…
Systematic analysis of the proton mass radius based on photoproduction of vector charmoniums
Xiao-Yun Wang, Fancong Zeng, Quanjin Wang
In this work, the cross-section of the reaction from the production threshold to medium energy is studied and systematically analyzed within two glu…
Near-threshold photoproduction of in two-gluon exchange model
Fancong Zeng, Xiao-Yun Wang, Li Zhang +3
The near-threshold photoproduction of is regarded as one golden process to unveil the nucleon mass structure, pentaquark state involving the charm quarks, and the poorly cons…
Fitting the trajectories of particles in the equatorial plane of a magnetic dipole with epicycloids
Fancong Zeng, Konstantin Kabin, Xiao-Yun Wang +1
In this paper we discuss epicycloid approximation of the trajectories of charged particles in axisymmetric magnetic fields. Epicycloid trajectories are natural in the Guiding Cente…
